How to damage a large companies reputation?

The company (in the technology sector) did something very wrong to a small group of people and I want as many people to know as possible. Since it is not a big group of people for now they outcry on social media is not that big but they are doing it over and over again. I wrote an article post where I report in a neutral way of their methods. The problem is I don't have a blog.
Now how do you think is the best way to let as many people as possible know about it? Is there any large blogs where I can publish the article? Also I was thinking to spread the article with mass planner on social media. Any other ideas?
